It can also be grown in the main crop season in north-western and west-central plains. The total tuber yield of Kufri Surya is at par with high yielding variety Kufri Bahar. This variety yields excellent defect free tubers with high proportion of large (>85mm) tubers suitable for processing into high quality French fries and chips. The reducing sugar content of tubers of this variety is less than 100mg/100g fresh weight and the tuber dry matter content is 20–21% at harvest.
